摘　　要：随着激光对抗技术的迅速发展,采用低能激光对电视制导实施散斑干扰已成为一种极具威胁的干扰形式,严重影响电视制导的跟踪效果。针对传统的电视制导跟踪算法在激光散斑干扰时跟踪效果不佳的问题,进行了抗激光散斑干扰的电视制导跟踪算法研究。首先设计激光散斑干扰模拟装置,在实验室条件下模拟产生激光散斑干扰,然后对当前主流的电视跟踪算法进行深入研究,重点对比分析其抗激光散斑的干扰能力。实验证明,粒子滤波跟踪算法具有较好的稳定性、鲁棒性和抗激光散斑干扰的能力。With the rapid development of laser countermeasure technology,the low-energy laser speckle jamming become a particularly aggressive way to TV guidance,seriously impacting the tracking effect of TV guidance.The traditional TV-guided tracking arithmetic doesn＇t have satisfactory target tracking performance under the laser speckle jamming.In order to solve the problem,we studied a TV-guided tracking arithmetic for antagonizing laser speckle jamming.A simulator was designed for laser speckle jamming,which could generate laser speckle in the lab.Then,the current TV-guided tracking arithmetics were studied with focus on their ability of antagonizing laser speckle jamming.The simulation experiment result showed that the particle filter tracking arithmetic has well stability,robustness and anti-jamming capability.
